I've used Qimage successfully for many years, first with a 10D and then a 5D.

Since switching to a 5D mark 2 some of my images appear corrupted when they are viewed or printed with Qimage. 

The corruption artifacts include: image will become black and white with many large obscuring bands traversing the image and this image will be a 3 x 3 (9 small images) composite of the original image.  The corrupted image will appear this way both in the thumbnail/preview and in outputed form from the printer.

Can someone help me?  Sometimes the images are prepped in LR, sometimes in ACR/PS CS3, sometimes in both.  They are 16 bit TIFFs.

I think Qimage is a jewel, but having experienced the repeating thumbnail problems, and now this, I am a bit on my heels over the program.

Thank you very much.
